Deep monsoon moisture made its push across southern Arizona, and several storms across the region turned severe with damaging wind gusts, quarter-sized hail and heavy rain.
Storms continued to develop well into the evening hours of Sunday and generally moved to the northwest. The strong winds associated with the storms picked up some blowing dust and reduced visibility to below one mile along the roadways.
An active monsoon pattern is setting up for the next several days with scattered storms possible across that area each afternoon and evening to start the workweek.
Scattered showers and thunderstorms that developed Sunday in the High Country lasted through the evening.
Storms in northern Arizona will produce moderate rainfall and gusty outflow winds up to 50 mph. The NWS said localized areas may see heavy rainfall exceeding one inch and small hail is also possible.
